Ke$ha also requested specific types of alcohol backstage, including 'a bottle of Don Julio or Patron Tequila, two bottles of Nice Cabernet and one bottle of vodka - Grey Goose preferred'.

The star's mother, Pete Sebert, has openly accused music producer Dr. Luke of contributing to her daughter's disorder, saying he made cruel remarks towards the pop star.

Dr. Luke, real name Lukasz Sebastian Gottwald, has denied these claims. He insists he has nothing but compassion for the young star, and has wished Ke$ha a quick recovery.

'These statements and allegations concerning Dr. Luke are completely false,' a spokesperson told Radar Online.'It is unfortunate that at a time Ke$ha is suffering immensely and trying to heal at a treatment center, her mother is taking this approach with the media. I give Ke$ha my utmost support and well wishes for a quick return to health.'
